“Are Values Clamped from 0.0 to 1.0? - No, you can use the full range supported. GL_RGBA32F_ARB, GL_RGB32F_ARB, GL_ALPHA32F_ARB, GL_INTENSITY32F_ARB, GL_LUMINANCE32F_ARB, GL_LUMINANCE_ALPHA32F_ARB for 32 bit floats.
GL_RGBA16F_ARB, GL_RGB16F_ARB, GL_ALPHA16F_ARB, GL_INTENSITY16F_ARB, GL_LUMINANCE16F_ARB, GL_LUMINANCE_ALPHA16F_ARB for 16 bit floats.”

[pyopengl] vbo
to use VBO with pyopengl, set ‘None’ as the pointer arg for glVertexPointer, not 0.
vboを使う時、pyeopeglではglVertexPointerのポインタにNoneを指定する。 0 ではない。

gl_feedback apparently NOT available
options are:

UPDATE:
vertex texture fetch is available on macbook early 2009, the number of texture units is 16.
GLint MaxVertexTextureImageUnits = 0;
